A balanced diet will depend on the types of food eaten over a period of time and the nutritional needs of the particular individual. The wider the variety of foods eaten‚ the more nutrients will be provided by them. It is now known

This is the reason why we chose lychee because of the nutrients that are Here so we used it as a research for our science investigatory project. We all know that the lychee fruit could be a sweet desert that can be served in our homes. But What we didn’t know about this fruit is that it could help

5/14/2009 Introduction The purpose of this study is to differentiate and identify two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The initial streak-plate procedure was performed and placed in the incubator at 37◦C for 24-48 hours. Upon

organs to detect and discriminate various types of taste such as sweet or bitter (Weiss et al.‚ 2011). When these organs come in contact with a food source‚ signals are sent to taste receptor cells. The activation of certain taste receptor cells by nutrients or chemical compounds have been found to stimulate the sense of taste (Breslin‚ 2013). This would help the organism initiate the appropriate feeding behavior such as rejecting a bitter food and accepting a sweet food (Chen‚ 2015). Invertebrates

of different concentration of protease. In this experiment‚ a plate of milk agar is needed for comparing the result of each sample. Circular wells were dug on the milk agar plates by the use of cork borer‚ and extracts could be put into the wells by dropper. One must note that milk-agar is white in color due to casein. If protease is present‚ casein will be digested by the enzyme giving a clear zone in the milk-agar plate. The size of the clear zone can help us to determine whether fruits differ
